当前我国许多县城正在进行抗震规划编制工作,本文结合地理信息系统(GIS),介绍了某县城城区抗震防灾规划的编制及基于GIS的抗震防灾决策系统的开发过程。根据对该规划区建筑物的震害预测,得出震后建筑物的破坏状况及经济损失、人员伤亡情况,为规划编制提供理论依据。 At present, many counties in our country are carrying out preparation work of seismic planning. In this paper, the author introduces the development of seismic disaster prevention plan and the development process of earthquake-resistant and disaster-prevention decision-making system based on GIS, combined with Geographic Information System (GIS). Based on the earthquake damage prediction of the buildings in the planned area, the damage status, economic loss and casualties of the buildings after the earthquake are obtained, which provides a theoretical basis for the planning.
